WlCK-ADJUSTER FO R O l L-STOVES SPECIFICATION forming part of Letters Patent No. 314,928, dated March 31, 1885.

Application filed November 18, 1854.

To all whom it may concern.-

Be it known that I, ROGER P. FROST, a citizen of the United States, residing at Fitchburg, in the county of \Vorcester and State of Massachusetts, have invented certain new and useful Improvements in Oil-Stove Burners, of which the following is a full, clear, and exact description, reference being had to the ac companying drawings, making part of this specification, in which- Figure 1 is a perspective view of my device with a wick in position for use. Fig. 2 is a bottom plan view with the wick removed. Fig. 3 is a longitudinal view through the line 00 0c of Fig. 2.

My invention relates to that class of burners more particularly adapted for use on oilstoves, but it may also be applied to oil-1a1npS of all kinds; and it consists of the combination of parts hereinafter explained and claimed.

To enable others skilled in the art to make and use my invention, I will now proceed to describe'the exact manner in which I have carried it out.

In the drawings, A represents the housing of the burner, which is preferably made of cast metal, and is provided with a slight hollow projection, a, on the opposite side to the handle, to receive and serve as a bearing for the end of the spindle b, on which is rigidly secured the metal feed roll B. In the top of the housing is an elongated openingfor the insertion of the fiat tube 6. The housing may be cast separately, or it may be cast in connection with thetop of the stove.

The feed-roll B is fluted its entire length, and securely fastened to the spindle, which has its near bearing in the side of the housing,

The rear or friction roll, D,which is of the same length with the feed-roll, is cut away at intervals, as shown at d, Fig. 2, to allow the free circulation of oil through the wick. This friction roll has its bearingsin the bent ends of the spring E, which is attached at its center to the housing, as shown in Fig. 2 of the drawings. The spring E secures a true and even pressure of the roll against the wick, and the roll is self-adj usting to any unevenness of the wick.

The metal thumb -piece F on the rear end of the spindle b is made in two sections, the

short distance of the housing, and with the free end of the wire bent at right angles to the spindle, and the end extending up to a height sufticient to be. brought in contact with the short projection g on the housing, as shown in Fig. 1. It is evident that the projection 9 might be on the wick-tube without departing from the spirit of my invention.

WVhen the slidingcap is in its normal condition, as shown in Fig. 1, it is clear that the feed-roll can only be turned until the wire G comes in contact with the stop g, thus limiting the distance the wick can be moved up or down in the wick-tube, and thus guarding against the liability of allowing the wick to be turned down into the stove. To give the feed-roll more than one revolution, it is only necessary to slide the cap of the thumb-piece outward on the spindle until arrested by the collar 1), when the free end of wire G will be withdrawn from possibility of contact with the projection g, and the spindle and feedroll may be freely revolved any number of times.

By the use of my feed-roll all danger of catching or cutting the wick is avoided, and this, in connection with the pressure-roll, insures the wick being turned upor down even- 1 y, while the pressure-roll, having its bearings in the spring, automatically adapts itself to any thickness of wick, and in case of knots or other obstructions in the wick the wick is nevertheless moved up readily and evenly.

I am aware it is not broadly new to employ a fluted roll and a rod carrying a series of toothed wheels for raising lamp-wicks.

I am also aware that two rods with wickwheels and adj Listing-springs have been used ICO for a similar purpose, and these features, there- 2. In a stove or lamp burner, the metal housing A, provided with the wick-tube O and projection g, in combination with the fluted feed-r011 B, spindle 1), metal thumb-piece F, made in sections, with the outer cap sliding on the spindle, and the wire G, all constructed to operate substantially as and for the purpose set forth.
